Title: Oxygen regulator
IPC: A62B9/02
Filed: 1957-06-14
Abstract: 841,218. Respiratory appliances. ARO EQUIPMENT CORPORATION. June 14, 1957 [Dec. 3, 1956], No. 18816/57. Class 81(2). An oxygen regulator for airmen comprises a main body including shut-off and demand valves and a diluter valve assembly enclosed in a casing Fig. 1, 18, and mounted on a panel 12 having slots through which project operating levers 35, 86 connected by linkage to the valves and the assembly. As shown diagrammatically in Fig. 10, the oxygen enters the regulator by an inlet 26 and passes through a first-stage reducing valve 20 to a demand valve 40 controlled through a lever 41 by the deflection of a diaphragm 42 subject to the reduction of pressure in a chamber B caused by inhalations of the user. The oxygen then passes to the mask via an injector 47 supplied with air which passes into a chamber F of the regulator through ports controlled by a rotatable disc valve 100, a valve 50 incorporating an aneroid 54, and a check valve 60. With increase in altitude, the aneroid closes the valve 50 so that eventually the flow of air is cut off and oxygen alone passes to the mask. If desired, the air supply may be reduced or cut off by operating a lever 105, Fig. 1, which controls the valve 100. A shut-off valve 30, disposed between the pressure regulator 20. and the demand valve 40, is operable by the lever 35. The controlling diaphragm 42 of the demand valve separates the chamber B from a space H formed by a second diaphragm 43 exposed to atmospheric pressure. The space H communicates with the outlet side of the pressure regulator 20 through a valve 90, which is opened by an aneroid 96 at high attitudes, and a duct 68. The valve 20, Fig. 6, is mounted in a cage 25 carrying a filter 29, composed in series with a filter 27 in the oxygen inlet 26, and at its lower end bears upon a spring-loaded diaphragm 22 subject on its underside to atmospheric pressure and on its upper side to the oxygen pressure in the chamber A. The shut-off valve 30 is controlled by the lever 35 through a bell-crank 37 Fig. 3A, one arm of which abuts the head 36 of the valve stem 34. The air inlet valve 100 Fig. 3, comprises a disc loaded by a spring 102 and formed with ports coacting with corresponding ports in a gasket 103, the disc being rotatable from a lever 105 through a link 104 connected to an arm 101 on the disc. The demand valve 40, Fig. 7, is controlled through a stem 15 bearing on a screw 55 carried by a lever pivoted at 51 and actuated by the diaphragm 42. The valve 40 may be moved to and held in its open position in an emergency by the pilot raising the lever 86 and through the mechanism 77, 78 pressing the diaphragm 43 against the diaphragm 42 and moving the lever 41 to open the valve

Title: Improvements in solid expanded coffee corn syrup mixture
IPC: A23F5/48
Filed: 1944-10-02
Abstract: 582,918. Coffee extracts. CLEVELAND, F. J. (Granular Foods, Inc.). Oct. 2, 1944, No. 18838. [Class 129] A coffee extract is combined with corn syrup, The coffee is treated to separate out volatile constituents of both condensable and relatively non-condensable characteristics, the volatile and relatively non-condensable elements being captured in corn syrup, to which the condensable elements and the extract 'of the soluble solids of the coffee residue are added. This mixture is then expanded under low heat and high vacuum to form a dry solid of sponge-like structure, which. is readily soluble. Separate roasted coffee is purified in order to eliminate those elements which develop obnoxious taste and aroma characteristics. Vapours and gases given off during roasting are caught and retained in the extract from the first-treated coffee. Steam is passed through ground coffee 11 in a sealed tank 10 and carries off the volatile constituents to a cooling coil 16. Vapours and gases from the final stage of roasting of coffee in a roaster 20 pass through a pipe 21, filter 22 to remove dust, and is led to the coil 16. The volatile elements are further chilled in a chamber 18, packed with ice and led to an insulated tank 31. Relatively non-condensable constituents pass through a pipe 35 into a coil 36 packed in carbon dioxide 37 and passed by a pipe 41 and nozzle 42 into the liquid corn syrup 43. The condensate 30, from which water may have been removed, is added to the corn syrup. To this mixture is now added the solution derived from passing hot water through the coffee 11 from which the volatiles have been removed. This hot water solution may be passed through a number of tanks 51, 52, containing ground and roasted coffee. The corn syrup may be diluted by water before the volatile elements are added. Coffee corn-syrup powder may be formed by' pouring the mixture prepared as described above, into a shallow pan in which it is boiled in a high vacuum, and bubbles are formed in the mixture. Repeated heatings causes the expansion of the mass until the bubbles burst into one another and break open at the surface to form an intercommunicating cell structure. Further heat is applied causing the mass to solidify, moisture being driven off. The resultant product is crushed and screened. Various proportions of coffee to corn syrup are given in the Specification. Roasted coffee beans may be plunged into the corn syrup containing the volatile constituents and afterwards withdrawn.
